Some time ago, I transcribed the Rice Index into HTML and posted it on the web. Not long after, I received a letter from a fellow who had some maps, clearly titled "Valuation Map", for a railroad which did not appear in the Rice Index. By then, I had noted a number of errors, mostly typographical, in the Rice Index. I decided I'd best obtain the 45 volumes of the Valuation Reports and look to see if some railroads had been omitted. In fact, I found one company which had been omitted, but not the one the letter was asking about.
Looking at the actual reports showed me that the Rice Index had a number of errors of some substance, so I set out to prepare a revised index. It also revealed some errors in the report volumes themselves. For instance, in one volume the page numbers shown in the Table of Cases is off by one page for all reports after the first.
Along the way, I decided to include the names of all predecessor companies mentioned in the reports. That is the work now in progress. I would be remiss if I did not express my gratitude to the staff of the library of the DuBois Campus of Penn State, especially Mrs. Anne Hummer.
Remember, it's not finished yet. A more polished introduction will replace this someday. In the meantime, here are the several pages of the index, as they currently exist. As in the Rice Index, there happen to be no company names beginning with X.
Oh! About that railroad which started this revision: Several states, chiefly in the western United States, piggybacked onto the ICC valuation project, requiring railroads to submit copies of the valuation data to their state tax authorities. The several railroads which were not subject to the ICC valuation had to prepare documents for their state governments. Apparently, that was the origin of the maps which puzzled my correspondent.
